MEXICO CITY – Residents of the Mexican capital will again have water flowing from their taps by late Tuesday after a days-long shutdown, the municipal government said.

The pumping of water will begin to fill cisterns and tanks in part of Mexico City on Wednesday, although service will not be 100 percent restored before the weekend, water system director Ramon Aguirre told Radio Formula.

“I am absolutely certain that today we will be given water,” Aguirre said.

Some 22 million people in greater Mexico City were without running water from Oct. 31-Nov. 3 due to a suspension of service to install a new pipe.

Although service was restored on Sunday, it was halted once again shortly afterwards due to a technical failure related to the installation of a so-called “K inverted” part, which is responsible for distributing water from the existing line to a newly installed one.
